High-contrast NACO H-band images of HD 61005, a) reduced with LOCI, b) reduced with ADI. The slits used for photometry are overlaid. The curved slit traces the maximum surface brightness of the lower ring arc, while the rectangular boxes enclose the streamers. In both images the scaling is linear, and 1″ corresponds to a projected separation of 34.5 AU. The arc-like structures in the background are artifacts of the observation and reduction techniques, and are asymmetric because the field rotation center was offset from the star. The region with insufficient field rotation is masked out. The plus marks the position of the star, the cross the ring center.
